The quarry dust is similar to the river sand in terms of density, specific gravity, grain size distribution, and chemical composition. However, it has a more angular shape and rougher in texture compared to the river sand. The water absorption of quarry dust is comparatively higher than river sand due to the higher fines content (particle sizes ...

It has been shown that dust particles of 20 microns or less can remain airborne for a very long time and can find their way on to and into machinery, into lungs, and also into areas outside the quarry itself. Dust particles less than 10 microns in size are invisible to the naked eye and can remain suspended in the air indefinitely.

Rock dust is a very popular soil additive especially with organic and permaculture groups. It is full of nutrients and adding it to soil will replenish all of the nutrients that agriculture has taken out of our soil. This process of adding nutrients back to soil is known as mineralization. This seems to make a lot of sense.
